Answer:

it they were asking probabilty of spinning red one time, like you know we would say 1/4.

but that want twice from us. so im multiplaying by itself.

(1/4)^2 = 1/16

good luck(:

It would be very least likely about 1/4

The college hiking club is having a fund raiser to buy new equipment for fall and winter outings. The club is selling Chinese fo

PolarNik [594]

Answer:

- the probability she will win the dinner for two is 0.016

- the probability she will not win the dinner for two is 0.984

- Lisa's expected earnings is $0.57

- Money she effectively contributed to the hiking club is $11.43

Step-by-step explanation:

Given the data in the question;

fortune cookies; $1 per cookies

club sold 743

a) Lisa bought 12 cookies. What is the probability she will win the dinner for two?

P( she will win ) = Number of cookies bought / Total number of cookies

P( she will win ) = 12 / 743

P( she will win ) = 0.01615 ≈ 0.016

Therefore, the probability she will win the dinner for two is 0.016

P( she will not win ) = 1 - P( she will win )

P( she will not win ) = 1 - 0.016

P( she will not win ) = 0.984

Therefore, the probability she will not win the dinner for two is 0.984

b) Lisa's expected earnings can be found by multiplying the value of the dinner by the probability that she will win. What are Lisa's expected earnings? (Round your answer to two decimal places.)$

given that value of dinner = $35

P( she will win ) = 0.01615

Lisa's earning = $35 × 0.01615

Lisa's earning = $0.57

Therefore, Lisa's expected earnings is $0.57

- How much did she effectively contribute to the hiking club? (Round your answer to two decimal places.)$

Lisa's contribution = Money she paid for cookies - money from expected earnings

Lisa's contribution = ( 12 × $1 ) - $ 0.57

Lisa's contribution = $12 - $0.57

Lisa's contribution = $11.43

Therefore, Money she effectively contributed to the hiking club is $11.43

I NEED HELP PLEASE! ITS DUE TOMORROW!! THANKS!

Answer:

Katie is not cheating. From the question, it sounds like Katie's spinner is 1-12. James has two dice so he has two sets of each number 1-6. This means that Katie can roll two numbers greater than six but James can only roll up to six. Using probability, I think there is a 50% chance that Katie's number will be bigger than James every time she spins. A fairer way would be for them both to play with the same dice or spinner.

Find the missing side or angle. Round to the nearest tenth. C=53° B= 80° a=2 b=[ ? ]

Degger [83]

9514 1404 393

Answer:

b ≈ 2.7

Step-by-step explanation:

The missing angle A is ...

A = 180° -53° -80° = 47°

The law of sines tells you ...

b/sin(B) = a/sin(A)

b = sin(80°)×2/sin(47°) ≈ 2.6931

Side b is about 2.7 units.
